Vulnerability discussion

Global initialization files are used to configure the user's shell environment upon login. Malicious modification of these files could compromise accounts upon logon.

Check content

Check global initialization files permissions: # ls -l /etc/.login /etc/profile /etc/bashrc /etc/environment /etc/security/environ /etc/security/.profile /etc/csh.login /etc/csh.cshrc If global initialization files are more permissive than 0644, this is a finding.

Fix text

Change the mode of the global initialization file(s) to 0444. # chmod 0444

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
